765552 divided by 45 
Let's see how many times 45 fits into 765552.

Going ahead to step 1:
7 divided by 45 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 45

On to step 2:
45 can be fit into 76 1 times, resulting in a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 45 away from 76, we end up with 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 45

Advancing to step 3:
45 can be fit into 315 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 315 from 315 to get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 45

Step 4:
The number 45 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 170.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 45

Let's proceed to step 5:
The number 45 fits into 55 1 times, leaving a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1701.0
Deduct 45 from 55 and we're left with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 45

Let's proceed to step 6:
102 divided by 45 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 17012.0
Deduct 90 from 102 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
The number 45 fits into 120 2 times, leaving a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 17012.2
If we subtract 90 from 120, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
When dividing 300 by 45, we get 6 with a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 17012.26
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
45 can be fit into 300 6 times, resulting in a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 17012.266
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 17012.266, with a leftover of 0.003.
